Use the mls qos map global configuration command to define the class of service
(CoS)-to-Differentiated Services Code Point (DSCP) map, DSCP-to-CoS map, the
DSCP-to-DSCP-mutation map, the DSCP-to-switch-priority map, the IP-precedence-to-DSCP map, and
the policed-DSCP map. Use the no form of this command to return to the default map.
mls qos map {cos-dscp dscp1...dscp8 | dscp-cos dscp-list to cos | dscp-mutation
dscp-mutation-name in-dscp to out-dscp | dscp-switch-priority dscp-list to switch-priority |
ip-prec-dscp dscp1...dscp8 | policed-dscp dscp-list to mark-down-dscp}
no mls qos map {cos-dscp | dscp-cos | dscp-mutation dscp-mutation-name | dscp-switch-priority
| ip-prec-dscp | policed-dscp}
Syntax Description cos-dscp dscp1...dscp8 Define the CoS-to-DSCP map.
For dscp1...dscp8, enter eight DSCP values that correspond to CoS values 0
to 7. Separate each DSCP value with a space. The range is 0 to 63.
dscp-cos dscp-list to
cos
Define the DSCP-to-CoS map.
For dscp-list, enter up to eight DSCP values, with each value separated by a
space. The range is 0 to 63. Then enter the to keyword.
For cos, enter the CoS value to which the DSCP values correspond. The
range is 0 to 7.
dscp-mutation
dscp-mutation-name
in-dscp to out-dscp
Define the DSCP-to-DSCP-mutation map.
For dscp-mutation-name, enter the mutation map name.
For in-dscp, enter up to eight DSCP values, with each value separated by a
space. Then enter the to keyword.
For out-dscp, enter a single DSCP value.
The range is 0 to 63.
dscp-switch-priority
dscp-list to
switch-priority
Define the DSCP-to-switch-priority map. This map generates the priority of
a request to the switch fabric when using a priority-aware switch fabric.
For dscp-list, enter up to eight DSCP values, with each value separated by a
space. The range is 0 to 63. Then enter the to keyword.
For switch-priority, the range is 0 to 3.
ip-prec-dscp
dscp1...dscp8
Define the IP-precedence-to-DSCP map.
For dscp1...dscp8, enter eight DSCP values that correspond to the IP
precedence values 0 to 7. Separate each DSCP value with a space. The range
is 0 to 63.
policed-dscp dscp-list
to mark-down-dscp
Define the policed-DSCP map.
For dscp-list, enter up to eight DSCP values, with each value separated by a
space. Then enter the to keyword.
For mark-down-dscp, enter the corresponding policed (marked down) DSCP
value.
The range is 0 to 63.
